Outdoor christmas decoration

So I got theese outdoor Christmas leds from China, solar powered ones. Like I expected, the lack of sun in Germany, especially on that side of the house where I intended to put them, was a big issue.

Another slight issue was that the children were so happy about the first snow, that they didn’t see it and ripped of the wire.

So my solution was to put everything on 4 AA batteries, and also on a Attiny85 microcontroller, and program the leds to automatically light up at 18:00 o’clock and turn off at 22:00.
